In preparation of blocking this service in the WebContent process, a sandbox extension should be issued if Safari's Develop menu is enabled.
This extension will also be dynamically issued to all WebContent processes, if the Develop menu preference changes, by observing this
preference.

* UIProcess/Cocoa/WebInspectorPreferenceObserver.mm: Added.
